Description

Self-lubricating concentrated laundry detergent product and preparation method thereof

Technical Field

The invention relates to the technical field of daily chemical products, in particular to a self-lubricating concentrated laundry detergent product and a preparation method thereof.

Background

Along with the continuous acceleration of the concentration degree of the Chinese washing and caring market and the transformation of consumption upgrading and consumer consumption concepts, the concentrated laundry detergent gel bead product accords with the concentration development trend of the washing industry. The concentrated laundry detergent bead product not only saves energy sources in the production, packaging, transportation and storage processes, but also reduces the generation of wastes. The concentrated laundry detergent gel bead product adopts quantitative split charging, is dissolved in water, has low foam and is easy to float, convenient to use, more convenient for the washing demands of consumers, and reduces the waste behavior caused by unreasonable dumping.

However, the concentrated laundry detergent beads have some defects, because the concentrated laundry detergent beads are packaged by adopting the polyvinyl alcohol water-soluble film, the polyvinyl alcohol water-soluble film is easy to dissolve in water and is influenced by air humidity, when the concentrated laundry detergent beads are stored in a high-humidity or long-term humidity environment, the concentrated laundry detergent beads are often stuck together and are not easy to separate, the packaged polyvinyl alcohol water-soluble film is broken due to forced separation, and liquid is leaked. In addition, if concentrated laundry detergent beads with different colors are placed together, cross color phenomenon can occur in the long-term storage process, the appearance of the product is affected, and the use feeling of consumers is reduced.

In the prior art, powder application is generally performed on the surface of the film. After the surface of the water-soluble film is coated with powder, the fluidity of the film is improved, and the film is easy to automatically split by a particle counter. The powder coated on the surface of the film is generally starch, but the starch is on the surface of the film for a long time, and can be putrefactive, so that the film has peculiar smell, thereby affecting the smell of the packaged concentrated laundry detergent and affecting the use feeling of the product.

Therefore, there is a need to design a concentrated laundry detergent product with self-lubricating action to lubricate the beads and prevent blocking and cross-color.
